Welcome to my world!

Backyard Birding in the Rio Grande Valley of South Texas: Surrounded by great birding destinations, our favorite patch is still the backyard (or the front), where we've seen more than 270 species of birds. Sit awhile, and watch the river and yard with us!

Sometimes I take a picture that isn't really good photographically-speaking, but that I like so much I keep looking at it. This is one of those. It's of a late-season warbler--Yellow, I suppose, but in autumn Peterson's references to "Confusing Fall Warblers" still paralyze me.

I was adjusting a hose that dripped into a new water feature I had pieced together out of spare parts when this little guy flittered into the water about six feet from me. I sat down and watched, snapping pictures.

What I like about the photo above is what makes it less than perfect--the focus is fuzzy, especially on the wings. But when the bird was in the water, my eyes certainly couldn't focus on such fast-moving, flittery wings. One foot is focused and one is not: he was shifting his weight like an excited child playing in a fountain. So that is the wallpaper on my laptop right now: a warbler looking precisely like it did for a while to my aging eyes on a really nice autumn afternoon.

Although it is still hot in the afternoons, temperatures usually reaching 90 or above, the birds finally know it's autumn even if we have trouble remembering this far south what autumn means to most of the country.

Wintering warblers such as Yellow-throated, Orange-crowned, and Black-throated Green (above) have arrived. An early (and rarer) Townsend's spent a couple of days.

Indigo Buntings (which have been a little late showing up, not even appearing for the Big Sit) are here in fairly large numbers. Some will stay the winter but most are already moving on.

Wintering sparrows have returned as well.

A Lincoln's sparrow enjoyed the new solar fountain.

Another sign of autumn here in the Rio Grande Valley are migrating Monarch butterflies, a few of which are passing through now on their way to Mexico. This picture, like the one of the Yellow Warbler in the bath, shows unfocused wings that are fluttering too fast for my point-and-shoot camera. I like the way the motion shows in the photographs.

But the surest sign of autumn is the music that filled the air early yesterday morning, and again today, a rolling, liquid sound that I could hear even inside, even when the windows were shut and the air-conditioner was on--Sandhill Cranes in the hundreds calling as they returned to the warmth of south Texas, calling me outside to enjoy our version of autumn.

This photo is also less than perfect--much less--but that's okay. The sun was just lighting a perfect fall morning, south Texas style, and hundreds of Sandhills filled the skies in waves of V's that just kept coming. We may not have autumn leaves or even cool temperatures, but we do have subtle changes that are just as cherished.

Postscript: Next Morning-- Again the waves of Sandhills called me outside. This time I made a video.

Eastern Screech-owls, Barn Owls, and Great Horned Owls
can be heard and sometimes seen in the night yard.

skimmers skimming; three species of owls, two of night-herons. Our Big Sit day was still night when I started tallying species from the upstairs back porch that was within our 17-foot circle. The river glowed from full-moonlight and fishing lights focused on its almost-still surface, providing just enough illumination to begin the count.

Every October, teams of birders gather at favorite birding spots to count the number of species seen or heard from a 17-foot circle in a 24-hour period, midnight to midnight. Most wait for daylight, but I always like to get a headstart since I'm sitting at my own window.

Rules for a Big Sit are easy: sit or stand in a 17-foot circle and count the different bird species you see. You can leave the circle and come back, but you count only those birds you see from the circle. The trick to a high count is to draw your circle near a variety of habitats, where you have clear view of sky, brush, and water and where man-made or natural habitats draw birds close enough to identify and mark on your list.
The Arroyo Colorado Audubon Society team tallied species again this year in my favorite place, our yard on the Arroyo Colorado. We were hoping to beat last year’s count of 86 species. (I know the Sit, sponsored by Birder's Digest, is billed as “noncompetitive,” but you really can’t take the competition out of birding, even if you’re only competing with yourself. Or with the birding group 40 miles upriver at Estero Llano Grande State Park—who beat us last year by one bird.)

I like to start a Big Sit at midnight, not just because I’m competitive (really, I’m not) but also because it’s one of the loveliest times for birding along the Arroyo. As soon as I step onto the porch, I hear Great Horned Owls hoo hoo-ing from one side of the yard to the other. I hear Screech Owls trill and Pauraques pu-wheeer!-- a circle of sound that seems visible.

As I watched the night river, Black Skimmers flew buoyantly just over the water’s surface, wingbeats steady, dipping down to skim the surface with a long lower mandible. The glow of the river illuminated the birds' silver-white breasts and underwing while the dark back and upper wings faded into the dark.

Across the river, barely visible unless I use binoculars to gather what light there is, a juvenile Yellow-crowned Night-heron peered from a low branch at the river’s edge. Longish legs and neck stretched toward the water, distinguishing it from the more numerous juvenile Black-crowned Night Herons that fished nearby. The crisp black and white of adult Black-crowned Night Herons stood out starkly against the shades of gray that blurred the river and bank.

Black-crowned Night Heron

Not far from a wading Great Blue Heron, a small white heron fished alone, a juvenile Little Blue: its feet not the gold of a Snowy Egret’s (which even in this gray world of the nighttime river bank would appear a lighter shade against the dark legs), but the same grayish green as its legs. Its beak was slim and pointed. I'd been looking for this Little Blue Heron, which for a week had been fishing right there, usually just before and just after dark. I never know if the birds I see everyday before a Big Sit will appear on Big Sit day, but right on schedule this one showed.

By dawn, several other Arroyo Colorado Audubon Society members had arrived to join the Big Sit at the house, parking on the road and walking up the driveway past the bird baths and feeders that could be seen from the circle through the open garage door. (No, I didn't stay up all night watching and listening, but I was up by 6:30 to greet more sitters and morning birds.)

Looking opposite the drive to the back yard, some of the Big Sitters kept an eye on the fence line across the river, a favorite perching place for many kinds of birds. Among the avian sitters were a Blue Grosbeak, Lark Sparrow, Groove-billed Anis, Red-Shouldered Hawk, Turkey Vultures, and a Ringed Kingfisher.

Getting a good count on Big Sit day sometimes depends on the weather, both on that day and for the previous week or so. For example, last year ducks, geese, Sandhill Cranes, and White Pelicans were already flying over the yard by the 2nd week of October. This year the hot weather seems to have delayed them a bit. Only the resident Black-bellied Whistling Ducks and a small group of Blue-winged Teal showed up. (A week later, however, I can hear geese flying over as I write this blog.)

On the day of this year's Big Sit the weather was varied, to say the least. It started out clear, but by mid-morning brief rain showers began alternating with sunny skies. Despite intermittent rain, afternoon temps climbed into the mid 90's, where the thermometer had been every afternoon for weeks. We were a little discouraged by then that our bird count was not climbing as well.

Rain didn't keep migrating hummingbirds away from the feeder that hung just inside the circle. Ruby-throated Hummingbirds (as well as a Rufous and Black-chinned) found the feeders even when it was raining. When skies turned blue again, the swarm just increased.

Buff-bellied hummers preferred native Turk's Cap.

A berrying Fiddlewood just outside the circle was a magnet for warring Northern Kiskadees, mockingbirds, and kingbirds. (These birds have not learned to share.) Both Long-billed and Curve-billed thrashers thrashed in the underbrush and sang from the trees.

Our most cooperative bird of the day was a Yellow-billed Cuckoo that posed and preened in a backyard Ash tree, spreading wings out to dry after a shower. (photo by Cheryle Beck)

A mid-afternoon thunderstorm cooled us down, but made it a little harder to see from the windows. By the time skies were blue again, the wind from the north, and temperatures in the high 70's, most sitters had gone home or on to another Big Sit.

Sitters left, but even more birds came out to enjoy the sun. This Ringed Kingfisher, sitting in a tree across the Arroyo, is just one of the three species of kingfishers that fished the river in the late afternoon after everyone else had gone home. Though this isn't a good photograph it is representative of the views we have on a big sit--far away but still exciting as we chase and twitch in the confines of a 17-foot circle.

I sat in the rocking chair and watched the river and sky til dark and beyond. What had started out a slow day ended with a higher count than any of our other years. At the stroke of midnight our list had 91 species of birds. The results are not all posted, but I think we'll be in the top ten again. Even without a Roseate Spoonbill or a Painted Bunting or some of the other birds we missed for the first time, we had a great time and ended with a good list. If I'd never seen or heard another bird after the owls at midnight, those would be enough for me.

The Arroyo Colorado Audubon Society birders have had our Big Sit in our yard three times previously: in 2001 (82 species); 2002 (89 species); and last year (86). All three years we have been among the top ten sites in the nation. We keep hoping to exceed 100 species--I know on a perfect day we could. Some years we have ducks and shorebirds; some years more warblers. Some years we have birders who are good at swallows or far-away fast-moving shorebirds headed for the bay; some years those seem to be nobody's specialties. This year we ended with 91 species even without some common ones like Indigo Buntings or Tri-colored Herons or Pyrrhuloxias (all of those were here on the following day, of course). Next year I'll brush up on far away ducks and faster-than-the-eye-can-see swallows. 100 species isn't impossible.

The "Weslaco Red Crowns" team of Big Sitters who were sitting up the Valley at Estero Llano Grande State Park (a World Birding Center site in Weslaco, Texas), are our friendly rivals. In fact, our teams overlap as birders take part in both counts. This year they beat us (in this noncompetitive competition) by eight for 99 species. 100 eluded them, too, but not by much. Way to go, Red Crowns! If we could combine our lists, we'd beat 100 by at least a couple of dozen.

To me this proves what I already think: the Lower Rio Grande Valley in Texas is the place to be if you love birds, birding, birders. Whether you are at Estero Llano Grande or another state park, a city park, a national wildlife refuge, a World Birding Center satellite site, or someone's backyard--whether you are here in the morning, at noon, or at midnight--you will have a memorable trip if you come to the Valley.

Harlingen's Rio Grande Valley Birding Festival is now less than a month away. Chair Marci Fuller, President Danny Hoehne, and all the other leaders and workers of the RGV Bird Fest are working hard to make this 18th Annual event the best ever. At this week's festival meeting we learned that registrations already exceed those of last year. That's not surprising--the field trips, the seminars, the trade show, the speakers are almost as great as our birds.

I attended the very first RGVBF eighteen ago and can't wait for this one. (The theme for this year's festival is The Big Year. You'll see why if you scope out the website here. )

It's not too late to register for the festival or to make travel arrangements. Anyone who loves birds or nature (or just great Tex-Mex food for that matter!) would love the Rio Grande Valley. Day or night, standing or sitting, the birding is great and the listing is easy. If the weather is not sunny just wait awhile--and in the meanwhile you could sit by my window by the Arroyo Colorado.

Yard List 2012

Despite an overcast and blustery day on January 1, we were able to window-bird for 46 species on the new year's list. By the end of January, we had 100 birds, exactly the "goal" we set. (Last year's list of 214 Yard Birds can be found in the post for December 31, 2011.)
